Development of Metal Nanoparticle-Doped Polyanilino-Graphene Oxide High Performance Supercapacitor Cells
Dywili, Nomxolisi Ruth (University of the Western Cape, 2018)Supercapacitors, also known as ultracapacitors or electrochemical capacitors, are considered one of the most important subjects concerning electricity or energy storage which has proven to be problematic for South Africa. ... -
Electrochemical poly(ProDOT) dendritic DNA aptamer biosensor for signalling interferon gamma (IFN-ɣ) TB biomarker
Sidwaba, Unathi (University of the Western Cape, 2017)Tuberculosis (TB) is an infectious disease that, despite all efforts devoted towards its eradication, remains a threat to many countries including South Africa. Current diagnostic assays do offer better performance than ... -
Electrochemiluminescence of novel polyanilino-rutheniumbipyridyl-imidazo phenanthroline and carboxy-difluoroboradiazaindacene luminophores
Molapo, Kerileng Mildred (University of the Western Cape, 2015)Electrochemiluminiscence, (ECL), is an electrochemically-induced process that leads to the generation of measurable luminescent signals at the electrode surface. The luminescent signals occur when electrochemically generated ... -
Graphenated electrode protocol for electrochemical nanosensing of 17β- estradiol as an environmental estrogeneous endocrine disruptor
Mohamed, Nuralli (University of the Western Cape, 2016)17β-Estradiol can be defined as an endocrine disruptor chemical with estrogenic activity, which can bind to the estrogen receptor in the body and potentially alter the normal physiological function of the endocrine ... -
Impedimetric and electrode kinetic dynamics of DNA aptamer nanobiosensors for estrogeneous endocrine disruptors
Olowu, Rasaq Adewale (University of the Western Cape, 2011)In this work, DNA aptamer biosensor systems were developed for the detection of l7p-estradiol - an estrogeneous endocrine disrupting chemical (EDC). Endocrine disrupting chemicals are group of compounds that impact negatively ... -
Microfluidic graphenised-paper electroanalytical devices (μGPED) for adsorptive cathodic stripping voltammetric detection of metal contaminants
Pokpas, Keagan William (University of the Western Cape, 2017)The need for clean, non-toxic drinking water supplies, free of pollutants and metal contamination is vital in impoverished areas and the developing world alike. With this in mind, the development of accurate, inexpensive, ... -
Molecularly imprinted polymer sensor systems for environmental estrogenic endocrine disrupting chemicals
Ntshongontshi, Nomaphelo (University of the Western Cape, 2018)There is growing concern on endocrine disrupting compounds (EDCs). The presence of drugs in water supplies was first realized in Germany in the early 1990s when environmental scientists discovered clofibric acid. Clofibric ... -
Novel aromatic dendritic-co-poly(3-hexylthiophene) composites for photovoltaic cell application
Ramoroka, Morongwa Emmanuel (University of Western Cape, 2021)Fossil fuels are part of fuels that are formed from natural processes and they are called non-renewable sources of energy. These include natural gas, coal and oil. They have been used for decades to produce energy globally. ... -
Pt Nanophase supported catalysts and electrode systems for water electrolysis
Petrik, Leslie F. (University of the Western Cape, 2008)In this study novel composite electrodes were developed, in which the catalytic components were deposited in nanoparticulate form. The efficiency of the nanophase catalysts and membrane electrodes were tested in an important ... -
Quantum dots-amplified electrochemical cytochrome P450 phenotype sensor for tamoxifen, a breast cancer drug
Feleni, Usisipho (University of the Western Cape, 2017)Breast cancer is regarded as the most common cancer in South Africa and its rate of occurrence is increasing. About one in every 31 South African women are at the risk of developing breast cancer and early diagnosis and ...
